从运转维修上防治3GR螺杆泵振动现年随着3GR螺杆泵在行业上的越来越强大的利用率，人们也开始更加好的研究有关于3GR螺杆泵的另外的一些特性。采用3GR螺杆泵来给我们的生活带来很多方便而且技术性也会得到越来越肯定的支持。尽可能低选用低转速3GR螺杆泵。尽管高转速3GR螺杆泵可以减少3GR螺杆泵的体积和提高效率，但有些高速3GR螺杆泵由于设计制造问题难适应高速运转的要求，运转稳定性差，其使用寿命较短，故从运行方面考虑，为了减少廷加损失和延长运行寿命，还是选用低转速3GR螺杆泵较为有利。
From the operation control of 3GR repair of screw pump vibration, with the utilization of 3GR screw pump in the industry more and more powerful, people began to have some additional characteristics about 3GR screw pump research more good. 3GR screw pump was used tobrings a great convenience to our life and the technology will also get more and morepositive support. As low as possible use low speed 3GR screw pump. Despite the high speed 3GR screw pump can reduce 3GR screw pump volume and improve efficiency, but some high speed 3GR screw pump because of design and manufacture problems difficult to adapt to the high-speed operation requirements, operation stability, its service life is short, so from running into consideration, in order to reduce the tingha losses and prolong the service life,or choose relatively favorable low Rev 3GR screw pump.
防止小流量运转或开空3GR螺杆泵。操作上不允许使用进口阀门调节流量，运行情况下进口阀门一般要全开，控制流量只能调节出口阀门，如果运转过程中阀门长期关的过小，说明3GR螺杆泵的容量过大，运行不经济且影响寿命，应当改选3GR螺杆泵型或降低转速运行。泵良好的密封状态，密封不好的泵除了造成跑冒滴漏损失以外，最严重的问题是流体进入轴承内部，加剧磨损，引起振动，缩短寿命。
Prevent small flow operation or open air 3GR screw pump. The use of imported valvesregulate the flow operation not allowed, the valve inlet running normally fully open, flow control can adjust the outlet valve, if the valve operation process of
